AI Extensions
AI Extensions are how you let Raycast AI take action across your installed extensions. Once an extension exposes its commands as tools, you can mention it from Quick AI, AI Chat, or Root Search and the AI figures out which tool to call, with what arguments, and runs it for you.
Discover AI Extensions
Built-in AI Extensions
Raycast includes several built-in AI Extensions that work with Raycast itself, the data on your device, and the apps you use on Mac or Windows. The badge next to each one shows the platforms it's available on:

Install AI Extensions
More AI Extensions are available on the Raycast Store. Open the Store from Root Search and filter by the AI Extensions category in the Navigation Bar using ⌘ / Ctrl P to see only the extensions that include tools. These cover everything from project trackers and music players to image editors and home automation.
On iOS, you can't install community-created AI Extensions, but you can extend Raycast AI the same way by connecting MCP servers. @-mention them in chat exactly like the built-in extensions above.
Using AI Extensions
Type @ in AI Chat, Quick AI, or Root Search and a list of every installed AI Extension appears. Pick one and chat in natural language. The AI chooses the right tool and shows you the call as it happens. Example prompts:
@linear what's assigned to me this sprint?@calendar block out 2 hours tomorrow morning for deep work@github pull requests waiting on my review@spotify play something mellow but not sad
You can also chain them in a single prompt: @calendar @things any free slots tomorrow that I could use to clear overdue tasks? and the AI will analyze both before answering your request.
Permissions
By default, Raycast asks for approval before running any tool from an AI Extension. You can change the default option in Raycast Settings → AI → Permissions, or override it for a single chat from the AI Chat's Chat Settings menu.
Manage AI Extensions
Each installed extension has its own section in Raycast Settings. Select one and you'll see the list of individual commands and the Ask tool it exposes. The Ask tool includes a free-text Custom Instructions field. Use it to steer the extension's behavior, for example "default my Linear queries to the Platform team" or "never schedule meetings before 10am." The AI reads these instructions whenever it considers using that extension's tools.
To remove an AI Extension entirely, uninstall the extension either from the Store or in Raycast Settings; its tools disappear from @-mentions immediately.
